Abstract

L'invention concerne des procédés, des systèmes et des dispositifs pour des communications sans fil qui permettent d'indiquer des informations de commande de puissance de transmission à un équipement utilisateur (UE) pour une planification semi-persistante (SPS) des transmissions dans des intervalles de temps de transmission courts (TTI) provenant de l'UE, ainsi que de configurer des transmissions de signaux de référence dans des transmissions SPS de TTI courts. Un UE peut être configuré avec des informations de commande de puissance en liaison montante pour des transmissions SPS qui utilisent des sTTI qui sont séparés de la commande de puissance de liaison montante pour les TTI plus longs. Un UE peut recevoir les informations de commande de puissance et les appliquer dans les transmissions SPS qui utilisent des sTTI. La puissance de transmission de liaison montante pour des transmissions sTTI de la SPS peut être indépendante de la commande de puissance pour les transmissions sTTI régulières et indépendante de la commande de puissance pour les transmissions à longs TTI. Des UE peuvent appliquer un décalage cyclique à des signaux de référence transmis dans des transmissions de la SPS selon une configuration de la SPS, plutôt qu'un décalage cyclique indiqué dans une commande d'activation de la SPS.
